    The authentication managing database 208 stores and manages identification information for identifying various types of mobile telephone terminal, and has a function of proceeding with authentication procedure, based on this identification information, for a mobile telephone terminal represented by the mobile telephone terminal 1. The authentication procedure is advanced by the function of the authentication managing database 208 when the response information that the driver responding means 205 generates under a communication control that the communication controlling means 204 implements is transmitted to the mobile telephone terminal 1. Thereby, even if unauthorized use utilizing the module is attempted, in the step of transmitting the driver to the mobile telephone terminal 1, the unauthorized use can be prevented. Here, examples of unauthorized use are use of the mobile telephone terminal 1 by a stranger masquerading as the true user, remodeling of the module by mounting a particular program onto the module to change or destroy the functions of the base station 2 and the like.

    The mounted driver managing database 209 stores and manages identification information for identifying various types of mobile telephone terminal, has a function of managing, based on the identification information, a driver mounted on a mobile telephone terminal represented by the mobile telephone terminal 1. The communication controlling means 204 is characterized by exerting communication control to read out a driver necessary for the update from the later described driver storing means 210 so that the driver is transmitted to the mobile telephone terminal 1 when conditions that allow an update of the driver mounted on the mobile telephone terminal 1 are fulfilled under the management of the mounted driver managing means 209.
  • [0054]
    “Conditions that allow an update of the driver” is considered to specify a driver necessary for booting a module connected to the connection part 106 at the time of reception of request information from the mobile telephone terminal 1, and for the driver to differ from the latest driver stored in the driver storing means 210.

    Here, the above described mode is a best mode for carrying out the present invention, but is not intended to establish any confinement. Therefore, within a range that will not change the points of the present invention, this mode can be transformed variously.
  • [0059]
    For example, the detachably attachable module is not limited to a camera, but may be a liquid crystal screen. In this case, a connecting part for attaching the liquid crystal screen is to be provided to the mobile telephone terminal of the present mode in advance. All needed is just to dismount the already-attached liquid crystal screen and attach a liquid crystal screen (for example, a liquid crystal screen corresponding with a newly updated driver) having functions different from the liquid crystal screen.
  • [0060]
    Real-time comprehension on needs of users for additions/changes of functions provided to the mobile telephone terminal of the present invention will become feasible and development/expansion of a service business based on those needs is anticipated.
